No Native 4K Gaming
For all its boasting about being able to deliver 4K graphics for video games, it seems a bit strange that the PS4 Pro won’t actually have native 4K gaming. When Sony says that the PS4 Pro will be able to show off beautiful 4K resolution for their supported titles, what this means is that the system will rely on “graphic rendering” techniques to upscale the resolution for video games. The system itself is not programmed for 4K output.
It’s still going to be a big graphical upgrade from the PS4, without a doubt, but it’s definitely worth noting that the 4K visuals you see on the Pro are not native. Also, if you really want to take full advantage of the PS4 Pro and make sure that all your games look the best they can possibly be, you’ll need to have a 4K TV for all that pixel goodness.
